Astm E125 Reference Photographs Pdf Free Download Official

Reference radiographs are images that serve as a standard for comparison when evaluating the quality of steel castings using radiography (x-ray). These images show various types of discontinuities, such as porosity, inclusions, and shrinkage, that can occur in steel castings. By comparing the radiographs of a casting being evaluated to the reference radiographs, inspectors can determine the severity of any discontinuities and make informed decisions about the acceptability of the casting.
